Hi
I have exactly the same issue with a desktop.
Exactly same error message and behave, I tried the standalone installer too and it quits installation with the same error message. The network agent is installed and working, I see the same "Critical" message in the cloud management, because the anti-virus is missing.
I tried to change the file system permission (force to renew the rights of "SYSTEM"), but on one part Windows 10 don't want me to change it (C: or C:\Program Files) and on the other "SYSTEM" has the rights needed. I think if there would a problem with it, then the network agent would also not install.
Free space on drive C: is 27.4 GB, sfc /scannow and DISM do not show any error.
I hope there is a solution coming, today I do not see any way to install Kaspersky on this desktop.
Thank you too for help.
